The invention provides a collapsible intermodal container (10, 10', 10"), comprising: first and second opposing side walls (12, 14), the first side wall (12) extending substantially parallel to the second side wall (14), each of the first and second side walls (12, 14) having a lower end portion (12b, 14b) and an upper end portion (12a, 14a); an upper wall (16) hingedly attached to the upper end portion (12b) of the first side wall (12); and a lower wall (18) hingedly attached to the lower end portion (14a) of the second side wall (14). The collapsible intermodal container (10, 10', 10") is configurable between: an erected configuration, in which the upper wall (16) extends from the upper end portion (12a) of the first side wall (12) to the upper end portion (14a) of the second side wall (14), and the lower wall (18) extends from the lower end portion (14b) of the second side wall (14) to the lower end portion (12b) of the first side wall (12), such that the first and second side walls (12, 14) are spaced apart by a first distance (D1) to define an interior (28) for storing goods; and a collapsed configuration, in which the upper wall (16) extends downwardly from the upper end portion (12b) of the first side wall (12), and the lower wall (18) extends upwardly from the lower end portion (14b) of the second side wall (14), such that the first and second side walls (12, 14) are spaced apart by a second distance (D2) which is less than the first distance (D1).
